CHAIN FASTENER.

applicati@ ined May 24,

The present invention is concerned with the provision of a chainfastener which may iave a wide range of utility in the arts but which ispeculiarly suited for attaching the cross tread members of an automobiletire chain to the annular runs thereof.

An object of the invention is to provide a device of this characterwhich will notv only securely lock the cross tread elements in place butwhich may be applied and removed with facility and expedition.

Further objects of the invention are to provide a chain fastener ofthecharacter not-ed above which will be. of simple, practical construction,which will be rugged, durable and efficient in use and which may bemanufactured with comparative economy.

VVith the above noted and other objects in view, the invention consistsin certain novel 'features of construct-ion and combinations andarrangements of. parts as will be more fully hereinafter described andset forth inthe claims.

The invention may be more fully understood from the accompanyingdrawings, wherein- Figure 1 is a plan view of a chain fastener embodyingthe present invention, showing the fastener in closed and lockedposition and indicating in dotted lines the cross tread and annularchain connected thereby; Y A

Figure 2 is a transverse sectional view on the line 2 2 of Figure 1;

Figure 3 is a plan view of the chain fastener showing the same opened toreceive a link of the annular chain and indicating in dotted lines thefastener oppositely bent to receive a link of the cross tread chain;

Figure 4 is a longitudinal sectional view on the line 4-4 of Figure 1;and

Figure 5 is a similar view illustrating the fastener open.

The fastener element of the present invention, generally speaking,includes an approximately oval link portion 10, theV ends of which areadapted to be engaged with a link 11 of ,a cross tread chain and a link12- of an annular chain, respectively. At approximately the centralportion of one of its sides, the link is formed with an opening 13,through which the links 12 and 11 are adapted to be passed. A. springtongue 14 normally closes the opening 13, and the when. the tonguehasbeen retracted.

The slid'able element includes an approxiserial No. iiifiia.

on the link 10 to uncover the opening mately channel shaped memberformed with 'an intermediate portion 15 and upstanding side iianges 16having pairs of' aligned openings therein for thereception of the sidesof the elongate-d link 10. Preferably, the spring tongue 14 is integralwith the channel shaped member and constitutes a re-.

versely bent extension of the intermediate portion 15. A lug 13 struckinwardly from one of the flanges 17 limits the outward 'springingmovement of the tongue 14, and the rounded pro]ecting end 19 of thetongue offers aconvenient hand hol-d for manually depressing the tongueto permit sliding movement of the channel member 'on the link.v

In Figure 1, I `have shown the .sliding member in its intermediateposition with the' tongue 14 disposed in the break 13 of the link andeffectively blocking relatively sliding movement of the link and thechannel member. To permit such movement, the free end of the tongue ispressed toward the intermediate portion 15 of the link, as shown indotted lines inY Figure 2, so that the tongue clears the ends of thelink. Channel member 15 may then be shifted in either direction relativeto the link 10, as indicated in Figures 3 and 5. The extent of slidingmovement of the channel member relative to the link is sufficient toexpose the opening 13 at either si'de ofthe channel'member de` pendingupon which direction such member is slid. lVith the channel member inone extreme position, as shown in Figures3 and 5. the link 12 of thecross chain may be entered into the link 10, and with the channel memberand link relatively slid to their `opposite extreme position indicatedin dotted y lines in Figure 3, opening 13 will be dis posed on theopposite side of the channel member and the link 11 may be entered intothe link 10. After the link 10 has been engaged with the two links 11and 12, thev tive sliding movement of the Alink and channel member.

Varinuscha'nges and alterations might be ,u y made 1n the general formand arrangement of the parts described Without departing from theinvention, and, hence, I do not Wish to limit myself to the precisedetails set forth, but shall consider myself at liberty to make allchanges and alterations which fairly fall Within the spirit and scope ofthe appended claims.

I claim:

l. A chain fastener including an elongated rigid loop-like link, thesides of which are parallel and one of which is formed with an openingtherein, a member slidable on the link and including a spring tongueadapted to snap between the ends of the link and block said opening,said sliding meinber including a ehannelled element, the side flanges ofwhich arey formed with align-ed openings receiving -the two parallelside pieces of the link, and the intermediate p0rtion of which is formedWith a reversely bent extension constituting the Spring tongue. y

2. A chain fastener including an elongated loop-like link, the sides ofwhich are parallel and one of which is formed with an opening therein, amember slidable on the link and including a spring tongue adapted tosnap between the ends of the link and block said opening, said slidingmember including a channelled element, the side flanges of which areformed with aligned openings receiving the two parallel side pieces ofthe link, and the intermediate p0rtion of Which is formed With areverscly bent extension constituting. the spring tongue and extendingbeyond the ends of the flanges to offer a handle for depressing thetongue to permit relative sliding` movement of the link and channelledmember.
